God has recently helped me to see that I don't have to understand to believe, because when I believe, it is then that I understand. 

When I believe that He loves me, I accept it, when I accept it, I experience it, when I experience it, my heart understands and knows unconditional love. 

I also don't have to understand to believe because God truly is working for my good and if He says no to something then I know that it must not be the best thing for me. 

Of course I want to understand why things happen or don't happen but before He tells me why, I can trust His love for me and His perfect timing.
